If people want the version information in the initial response line, then
we could put it there, and like that, instead of a capability line. This
would then mean there's no reason at all to require the lines to be
ordered.

Pre-4 defines the version numbers as just that, integers. Since the message
is "I support this one and that one and that one", I would suggest using +
or & rather than comma:

    [C] CAPABILITIES
    [S] 101 2+3+7 I'm talented, I am. Here's the capability list.
    [S] READER
    [S] OVER MSGID
    [S] HDR
    [S] .

Preferences from others? VERSION line with spaces, or argument to the 101
response with plus signs?

But I don't. In particular, I don't want "NNTPv2 NNTPv3" as a capability
line.
